          """ Return a polygon that is a smaller and smoothed approximation of Ves.Poly, useful for excluding the divertor region in a Tokamak
  
          For some uses, it can be practical to approximate the polygon defining the Ves object (which can be non-convex, like with a divertor), by a simpler, sligthly smaller and convex polygon.
          This method provides a fast solution for computing such a proxy.
  
          Parameters
          ----------
          RelOff :    float
              Fraction by which an homothetic polygon should be reduced (1.-RelOff)*(Poly-BaryS)
          ZLim :      None / str / tuple
              Flag indicating what limits shall be put to the height of the polygon (used for excluding divertor)
          Spline :    bool
              Flag indiating whether the reduced and truncated polygon shall be smoothed by 2D b-spline curves
          Splprms :   list
              List of 3 parameters to be used for the smoothing [weights,smoothness,b-spline order], fed to scipy.interpolate.splprep()
          NP :        int
              Number of points to be used to define the smoothed polygon
          Plot :      bool
              Flag indicating whether the result shall be plotted for visual inspection
          Test :      bool
              Flag indicating whether the inputs should be tested for conformity
  
          Returns
          -------
          Poly :      np.ndarray
              (2,N) polygon resulting from homothetic transform, truncating and optional smoothing
